Boat trailer having aluminum adjustable bunks

Abstract

A boat trailer formed of aluminum sections includes aluminum bunks formed of simple T shaped components bracketed to the trailer support assembly in an adjustable fashion. The bunks can be one piece or two piece bunks. In the case of two-piece bunks, standard components can be used for both the base part and the cross part.

What is claimed as new and is desired to be secured by Letters Patent of the United States is:  
     
       1. A boat trailer comprising: 
       an aluminum or aluminum alloy support assembly;  
       a plurality of road wheels for supporting said support assembly;  
       a hitch mechanism for hitching said support assembly to a vehicle; and  
       a plurality of bunks supported by said support assembly for supporting a boat hull, said bunks extending longitudinally substantially in the direction of the length of the trailer, wherein at least one of said bunks is at least in part formed of aluminum or an aluminum alloy, wherein said at least one bunk has a substantially T shaped cross section,  
       wherein said substantially T shaped cross section is comprised by a substantially vertically oriented base part mounted to said support assembly, and a cross part for supporting a boat hull, said cross part being pivotally mounted to said base part, further including at least one bracket mounting said base part to said support assembly.  
     
     
       2. The boat trailer of claim  1 , including a protective cap mounted to a top of said cross part. 
     
     
       3. The boat trailer of claim  1 , wherein said cross part extends substantially horizontally. 
     
     
       4. The boat trailer of claim  1 , wherein said cross part extends at an angle to a horizontal direction. 
     
     
       5. The boat trailer of claim  1 , wherein said base part comprises an elongate plate. 
     
     
       6. A boat trailer comprising: 
       an aluminum or aluminum alloy support assembly;  
       a plurality of road wheels for supporting said support assembly;  
       a hitch mechanism for hitching said support assembly to a vehicle; and  
       a plurality of pivoting bunks supported by said support assembly, said bunks extending longitudinally substantially in the direction of the length of the trailer, wherein at least one of said bunks is comprised of aluminum or an aluminum alloy, and wherein said at least one bunk has a substantially T shaped cross section with a base part and a freely pivoting cross part.
